When I first started using Trello, I subscribed to the "Trello Resources" board. Whenever I click the "Notifications" button in Trello, I get a bunch of Resources notifications. I think I unsubscribed from the notifications in "Board Options" and "List Options", but the "Trello Resources" notifications still flood my notifications. What I can I do to fully unsubscribe from that board?

EDIT: I realized I'm not subscribe anymore, but all of the notifications are still present. How can I clear those? They're irrelevant and a bit annoying.

The Android App has a Clear All Notifications link that you can use. I am sure other apps allow the same thing. This is also easier than using the desktop browser version which wants you to view notifications before it clears them.
